This document suggests that "a formalized joint military-civil doctrine approach will greatly enhance the military's ability to execute disaster assistance operations. Developing doctrine should include manning levels for the various agencies, appropriate administrative staffing and equipment, and suggested task organization structures for the JTF (engineer, logistics, security, communications, medical and liaison). The doctrine should also include reference to policy publications and technical manuals related to the specific types of disaster. Army and joint interoperability with civil, state, and federal agencies needs refinement so the Army can be a knowledgeable participant in disaster assistance. Specific guidance is needed in deployment operations, assessment teams, task organization, and required materiel and staff manning levels."
